Abstract
The utility model discloses a compensation type alternating current voltage stabilizer. The compensation type alternating current voltage stabilizer comprises a single chip microcomputer and a sampling converting unit which are connected. The compensation type alternating current voltage stabilizer is characterized in that when external voltage U1 is fluctuated or a load current is changed, the external voltage or the load current is converted through the sampling converting unit and is input to the single chip microcomputer for numerical value comparison; an alarm unit, an adjusting unit and a protecting unit are respectively connected with the single chip microcomputer; the adjusting unit is changed over into a compensation unit through the voltage zero-passage synchronous pulse, the compensation voltage value is changed through the compensation unit, and therefore the purpose of stabilizing output voltage U2 can be fast achieved. The voltage stabilizer is high in voltage stabilizing precision and efficiency, fast in response and strong in load carrying capacity.
Description
Technical field
The utility model relates to a kind of voltage stabilizer, is specifically related to a kind of compensation type ac voltage stabilizer.
Background technology
At present more to the research of direct current miniwatt constant current method, and less to the research that exchanges the constant current method.Ac current regulator mainly adopts following methods:
1, realize current stabilization with the thyristor regulating circuitry phase with feedback system, but, because be to adjust cutoff angle, will make sinusoidal wave serious distortion;
2, adopt feedback system to control servomotor, regulate the circuit of automatic coupling voltage regulator composition and realize current stabilization, but, because the machinery inertial of motor and kinematic train is regulated the speed slow and easily produces vibration, be difficult to realize stable adjusting;
3, take ferromagnetic element as adjusting the current stabilization circuit of element (magnetrol), its weak point is: because the large response time of magnetic inertia is longer, magnetic system can produce serious wave form distortion, and the power factor of system is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of compensation type ac voltage stabilizer, and this voltage stabilizer precision of voltage regulation is high, efficiency is high, response is fast, carrying load ability is strong.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Compensation type ac voltage stabilizer, comprise single-chip microcomputer and sample conversion unit, described single-chip microcomputer is connected with the sample conversion unit, it is characterized in that, when described sample conversion unit is changed by 1 fluctuation of outside voltage U or load current, carry out respective value relatively in the input single-chip microcomputer after the sample conversion cell translation, described single-chip microcomputer also respectively with alarm unit, regulon and protected location are connected, under the effect of voltage zero-cross synchronizing pulse, switch to compensating unit by regulon, and change the bucking voltage value by compensating unit, thereby reach rapidly voltage U 2 purposes of stable output.
The beneficial effects of the utility model are: this voltage stabilizer precision of voltage regulation is high, efficiency is high, response is fast, carrying load ability is strong.
